It enables PLL output (new functionality in H616). Without this only clocks which are child of PLL_CPUX and PLL_PERIPH0 would work (set up by U-Boot).

That way clocks will be initialized earlier and it will be actually possible to register both timer peripherals (once DT nodes are added). If pdev or dev is ever needed, two stage initialization can be made later.

I'm pretty sure that's not intended usage but > until we know better, it's ok imo. Ah right, the output enable bit. I was wondering if the A100 solution would better here: use bit 27 as the .enable value, and actually enable (bit31) all PLLs here. Or we add another field, maybe a flag, to allow the kernel to decide which bit to use. Clement suggested something like that on IRC. But for now I can surely just set bit 27 here as well. >> + writel(val, reg + pll_regs[i]); >> + } >> + >> + /* >> + * Force the output divider of video PLLs to 0. >> + * >> + * See the comment before pll-video0 definition for the reason. >> + */ >> + for (i = 0; i < ARRAY_SIZE(pll_video_regs); i++) { >> + val = readl(reg + pll_video_regs[i]); >> + val &= ~BIT(0); >> + writel(val, reg + pll_video_regs[i]); >> + } >> + >> + /* >> + * Force OHCI 12M clock sources to 00 (12MHz divided from 48MHz) >> + * >> + * This clock mux is still mysterious, and the code just enforces >> + * it to have a valid clock parent. >> + */ >> + for (i = 0; i < ARRAY_SIZE(usb2_clk_regs); i++) { >> + val = readl(reg + usb2_clk_regs[i]); >> + val &= ~GENMASK(25, 24); >> + writel (val, reg + usb2_clk_regs[i]); >> + } >> + >> + /* >> + * Force the post-divider of pll-audio to 12 and the output divider >> + * of it to 2, so 24576000 and 22579200 rates can be set exactly. >> + */ >> + val = readl(reg + SUN50I_H616_PLL_AUDIO_REG); >> + val &= ~(GENMASK(21, 16) | BIT(0)); >> + writel(val | (11 << 16) | BIT(0), reg + SUN50I_H616_PLL_AUDIO_REG); >> + >> + /* >> + * First clock parent (osc32K) is unusable for CEC.

Yeah, Clément found a comment in the BSP U-Boot that suggests that the same die is used with different packages. The H700 is mentioned as a sun50iw9p1 there as well, and this one supports LCD, reportedly. > Not only here, > but everywhere. We can leave them out for now. Right, we can add them later, maybe using a new clock compatible, like we do for the H3/H5.
